I recently installed an LED strip light to replace a fluorescent lamp in my garage.
It works great and I highly recommend them, however, I am curious why there is such a noticeable delay between turning on the AC wall switch and the thing lighting. I have seen folks on here before reporting a significant delay between application of AC power and lighting, and in my case the delay is close to a second.
However, I can't really figure out why the long delay. It's not LED turn on time, that ought to be a lot less than an incandescent bulb and I realize there is a constant current driver in there, but again, I'd think that would only take something in the order of tens of milliseconds to wind up.
So what else could be going on?
I played with it a bit more, turning the power off and on quickly I can make it stay off for over two seconds. I'm starting to wonder if these things have some smarts built in with significant delays to ensure stability of supply before LED activation.
Just wondering if any of our readers have some commercial design experience in this department and can shed some light on any higher design criteria that others, like me, might not be aware of. Perhaps safety or lamp life issues or some such.
